Without doing an on-site forensic, did the legs lower onto a thick mat of long-leaf pine needles (I've slid badly on pine needles in the past)? If the jack's landing pads were lowered onto the teflon-like slippy needles on hard packed ground, they (one landing pad) could have just slipped out (like walking on ice), and caused a cascade of instability with the other pads/legs, and the weak point, the jack attachments, just let go one at a time (even well connected)....Just a thought....

I have personally watched the third leg of a three legged camper loosing footing on a patch of ice and folding under ... with much the same result.
I think the solution is in this line of thinking....it may not have been necessarily a weak jack attaching point but could have been a lack of traction with the jack plate that cause it to slide, placing way too much lateral force on the mounting point and leading to a cascading overload event?
